That is the claim made for the transept windows in Heinz Chapel, and old Pa Pitt accepts it until someone proves otherwise. They were created by the studio of Charles Z. Connick.

The windows trace Christian history down from Christ to American heroes like Abraham Lincoln, shown here freeing slaves with his Emancipation Proclamation.

Father Pitt’s very favorite detail in these windows is in the Lincoln pane. In fact it is one of his favorite details in any stained glass anywhere. You probably won’t even notice it as you look at the heroic figure of Lincoln, but here it is:

This scowling cartoon-villain plantation owner, furious that some Northern abolitionist scum has the temerity to interfere with his right to whip his own property, is the perfect background for Lincoln. One feels that the whole Civil War was worth the trouble just to make this man frown.
